Risk Assessment & Hazard Management Flashcards

In the hierarchy of controls, which option is the MOST effective way to manage a fall hazard?

Answer: Eliminating the need to work at height

Elimination removes the hazard entirely, so it ranks above engineering, administrative, and PPE controls.

A risk matrix typically rates the level of risk by combining which two factors?

Answer: Likelihood and severity

Risk is commonly estimated as the probability of an event multiplied by the severity of its consequence.

Which hazard is the main reason to set up an exclusion zone below a rope access worksite?

Answer: Falling objects striking people below

Exclusion zones keep the public and other workers out of the drop zone where tools or debris could fall.

When should the rescue plan for a rope access job be developed?

Answer: Before any work at height begins

A site-specific rescue plan must be in place, with the resources to carry it out, before anyone goes on rope.

A technician notices that the working rope is running over an unprotected sharp concrete edge. What is the correct immediate action?

Answer: Stop and install edge protection or re-rig to avoid the edge

Sharp edges can cut a loaded rope quickly, so work must stop until the edge is protected or the rope is re-rigged.

What does 'residual risk' mean in a job hazard analysis?

Answer: The risk that remains after control measures are applied

Residual risk is what is left after controls are applied, and it must be reduced to an acceptable level.

Which weather condition should most clearly cause rope access work to be suspended?

Answer: Lightning in the vicinity

Lightning is an immediate life-threatening hazard to people suspended on structures, so work must stop.
